cohesion and cohesive devices in a contrastive analysis between ge and esp texts
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
15 صفحه اولIR and UV Spectroscopic Analysis of C20 Carbon Nanostructures
Infrared (IR) and ultraviolet (UV) spectroscopic analysis of eight structural isomers of C20 carbon nanostructures, i.e. ring, tadpole, bow-tie, dumb-bell, spiro, propellane, bowl and cage, were performed at different levels of theory including semi-empirical (AM1 and PM3), Hartree-Fock (HF/6-31++G, 6-31++G**) and density functional theory (B3LYP/6-31++G, 6-31++G**). A broad range of IR spectra...
متن کاملNew aspects of low-coordinated organosilicon compounds: Thermal dissociation of disilenes into silylenes
Disilenes Tbt(Mes)Si=SiTbt(Mes)(Mes:mesityl) bearing an efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl(Tbt), were synthesized and found to be extremely stable toward oxygen and water. In spite of the stability, they underwent thermal dissociation into silylenes under very mild conditions (ca. 50’ C). Silylenes thus formed reacted with alkenes, alkynes, benzene, n...
متن کاملStructural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques
FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.
متن کاملIR spectroscopic study and DFT calculations on dibenzyltin dichloride
Benzyl chloride and tin powder were used to prepare dibenzyltin dichloride according to a literatureprocedure. In this study, IR spectroscopy, HOMO-LUMO energy gap, NBO analysis, polarizability,some geometrical parameters, natural charge and electrical potential of atoms, global hardness,electronic chemical potential, global electrophilicity index, and molar volume of dibenzyltindichloride were...
